Find the length of the shortest ladder that will reach over an 8-ft. high fence to a large wall, which is 3 ft. behind the fence.

Sketch the function f(x) = 2x - tanx over the interval [-π/2, π/2] using information such as

-domain/range

-y and x intercepts

-symmetry

-asymptotes

-all critical points (x,y) of max/min points

-increasing/decreasing intervals

-points of inflection

-concavity

a ball is thrown with a velocity of 20.0 m/s [30] and travels for 3.0 s before it strikes the ground. Find the distance it travels horizontally, the height from which it was thrown, the maximum height of the ball

During the first year of production, 8 000 000 tonnes of copper were extracted from a Peruvian mine. Production has declined by 8% each year since then.a.) What was the total mass of the copper mined during the first four years of production?b.) How many years will it take for production to fall below 100 000 per year? c.) If the production trend continues, how much copper will be extracted from the mine over its lifetime? 

A special event organizer wants to get the word out to 100,000 teens in the area about a concert coming up in three months. By posting the event on the musicians' website, 100 teens in the area will find out about the event in the first week. Research suggests that each of those teams will tell for new teens about the event, in those friends each hotel for more teens about it.

a.) how many times does this pattern need to continue until 100,000 teens know about the event?

b.) what assumption is made in order to answer part a?

The pilot of a red ferry boat, with a cruising speed of 12 km/h, wishes to sail north from Georgetown to Medan across the Strait. If the strait has a 3.0 km/h current flowing west, what course should the pilot set to compensate for the current?  If the distance from Georgetown to Medan is 100 km, how long will the sailing take???
